Binary Notation


A system of positional notation in which the digits are coefficients of power of the base 2 in same way as the digits in the conventional decimal system are coefficients of power of the base 10.
Binary notation employs only two digits, 1 and 0, therefore is used extensively in computers where the on and off positions of a switch or storage device can represent the two digits. In decimal notation <math>111 = (1 X 102) + (1 X 101) + (1 x 100) = 100 + 10 + 1 = one hundred and eleven. In binary notation 111 = (1 x 22) + (1 x 21) + (1 x 20) = 4 + 2 + 1 = seven.</math>
